UNIFIED IN-AIRFRAME-CATAPULT DEVICE AND ITS DRIVE Russian patent published in 2010 - IPC B64D1/02 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly to catapult device intended for suspending aircraft rockets. Proposed device comprises housing with units of attaching it to aircraft, ejection mechanism, rocket launching drive, onboard connector electrical connection of rocker with aircraft. Ejection mechanism represents front and rear discharge levers arranged to rotate on axles fitted in aforesaid housing. Axle of said front discharge lever is located nearby rocket rear lug, while that of rear discharge lever is located nearby rocket front lug. Said discharge levers are coupled by crank to synchronise their motion and support rocket attachment carriages pivoted on free extreme ends. Carriage fixed on rear lever is furnished with tripper arranged in carriage guides and articulated with front discharge lever. Note that both front and rear discharge levers are provided with stops. Power drive comprises housing with attachments components, hollow plunger with pyrocartridge accommodated therein, combustion chamber, and bunched conductor to feed electric pulse to said pyrocartridge. The latter has electric igniter with two filament bridges and represents a cylindrical cartridge with aspect ration λ=3…5 to allow filling with variable amount of fuel.

EFFECT: higher reliability of suspension, rocket transport and launching.
